Yes, but keep the medication in its original labeled container, carry a copy of the prescription, and be aware of each country’s import regulations for prescription drugs.

Diaminodiphenyl sulfone, commonly known by its generic name Dapsone, is classified under skin-care pharmaceuticals. It is supplied as oral capsules packaged in a bottle containing 1000 capsules. In Hong Kong, Dapsone is a prescription-only medication regulated by the Department of Health.
Dapsone belongs to the sulfone class of antibiotics. It inhibits the bacterial enzyme dihydropteroate synthase, which interferes with folate synthesis and halts microbial growth. In addition to its antibacterial activity, Dapsone exerts anti-inflammatory effects by reducing neutrophil chemotaxis and oxidative burst, which helps control inflammatory skin disorders. The drug is absorbed from the gastrointestinal tract, reaches peak plasma concentrations within a few hours, and has a relatively long half-life, allowing once-daily dosing in most patients.
These indications are approved by the Hong Kong Department of Health for the oral capsule formulation of Dapsone.
If you are taking other medications, supplements, or herbal products, inform your healthcare provider before starting Dapsone.
Because the package contains 1000 capsules, the duration of therapy will depend on the prescribed daily dose.
